解析試題分析：對反意疑問句的回答，無論問題的提法如何，如果事實是肯定的，就用yes，事實是否定的，就要用no。要特別注意陳述句部分是否定結(jié)構(gòu)，反意疑問句部分用肯定式提問時，回答yes或no與漢語正好相反。這種省略回答的yes要譯成“不”，no要譯成“是”。
例：—He likes playing football, doesn’t he? 他喜歡踢足球，是嗎？
—Yes, he does. / No, he doesn’t. 是的。/ 不是。
—His sister didn’t attend the meeting, did she? 他妹妹沒有參加會議，是嗎？
—Yes, she did. / No, she didn’t. 不，她參加了。/ 是的，她沒參加。
簡要總結(jié)反意疑問句19條：
1) 陳述部分的主語是I，疑問部分要用 aren't I.
I'm as tall as your sister，aren't I?
2) 陳述部分的謂語是wish，疑問部分要用may +主語。
I wish to have a word with you, may I?
3) 陳述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, little等否定含義的詞時，疑問部分用肯定含義。
The Swede made no answer, did he / she?
Some plants never blown (開花), do they ?
4) 含有ought to 的反意疑問句，陳述部分是肯定的，疑問部分用shouldn't / oughtn't +主語。
He ought to know what to do, oughtn't he? / shouldn't he?
5) 陳述部分有have to +v. (had to + v.)，疑問部分常用don't +主語（didn't +主語）。
We have to get there at eight tomorrow, don't we?
6) 陳述部分的謂語是used to 時，疑問部分用didn't +主語或 usedn't +主語。
He used to take pictures there, didn't he? / usedn't he?
7) 陳述部分有had better + v. 疑問句部分用hadn't you?
You'd better read it by yourself, hadn't you?
8) 陳述部分有would rather +v.，疑問部分多用 wouldn't +主語。
He would rather read it ten times than recite it, wouldn't he?
9) 陳述部分有You'd like to +v. 疑問部分用wouldn't +主語。
You'd like to go with me, wouldn't you?
10) 陳述部分有must 的疑問句，疑問部分根據(jù)實際情況而定。
He must be a doctor, isn't he?
You must have studied English for three years, haven't you? / didn't you?
He must have finished it yesterday, didn't he?
11) 感嘆句中，疑問部分用be +主語。
What colours, aren't they?
What a smell, isn't it?
12) 陳述部分由neither… nor, either… or 連接的并列主語時，疑問部分根據(jù)其實際邏輯意義而定。
Neither you nor I am engineer, are we?
13) 陳述部分主語是指示代詞或不定代詞everything, that, nothing, this, 疑問部分主語用it。
Everything is ready, isn't it?
14)陳述部分為主語從句或并列復(fù)合句，疑問部分有三種情況：
a. 并列復(fù)合句疑問部分，謂語動詞根據(jù)鄰近從句的謂語而定。
Mr. Smith had been to Beijing for several times, he should have been in China now, shouldn't he?
b. 帶有定語從句，賓語從句的主從復(fù)合句，疑問部分謂語根據(jù)主句的謂語而定：
He is not the man who gave us a talk, is he?
He said he wanted to visit Japan, didn't he?
c. 上述部分主句謂語是think, believe, expect, suppose, imagine等引導的定語從句，疑問部分與賓語從句相對應(yīng)構(gòu)成反意疑問句。
I don't think he is bright, is he?
We believe she can do it better, can't she?
15) 陳述部分主語是不定代詞everybody, anyone, somebody, nobody, no one等，疑問部分常用復(fù)數(shù)they，有時也用單數(shù)he。
Everyone knows the answer, don't they? (does he?)
Nobody knows about it, do they? (does he?)
16) 帶情態(tài)動詞dare或need的反意疑問句，疑問部分常用 need (dare ) +主語。
We need not do it again, need we ?
He dare not say so, dare you?
當dare, need 為實義動詞時，疑問部分用助動詞do + 主語。
She doesn't dare to go home alone, does she?
17) 省去主語的祈使句的反意疑問句，疑問部分用will you。
Don't do that again, will you?
Go with me, will you / won't you ?
注意： Let's 開頭的祈使句，后用shall we?
Let us 開頭的祈使句，后用will you?
Let's go and listen to the music, shall we?
Let us wait for you in the reading-room, will you ?
18) 陳述部分是"there be"結(jié)構(gòu)的，疑問部分用there省略主語代詞。
There is something wrong with your watch, isn't there?
There will not be any trouble, will there?
19) 否定前綴不能視為否定詞，其反意疑問句仍用否定形式。
It is impossible, isn't it?
He is not unkind to his classmates, is he?
這里因為陳述部分有few故后半部分用肯定形式，又因為前面用動詞can，故后面用can,應(yīng)選D。
